A supplier is anyone you buy from on credit. Every purchase, purchase return and supplier payment is linked to one supplier, and the supplier page shows the running balance you owe.

Add a supplier
Section titled “Add a supplier”- Open Purchasing → Suppliers and select Add Supplier.
- Enter the name (required), and optionally email, phone and address.
- Add the supplier’s tax registration number so it prints on debit notes and is available for tax reports (India: the supplier’s GSTIN).
- Add bank name and bank account to keep payment details at hand, and payment terms (days) so new purchases get the right due date.
- Select Save.
